First of all I want to say that since getting tinnitus I'm kind of paranoid toward sound therapies with weird sounds and stuff like that but I decided to give Tinnitus Mix a go after reading most of the posts made here.
After listening to this ''screeching'' Tinnitus Mix (actually reminded me a bit of the video tape on ''The Ring'') for 1 hour and 15 minutes it feels like my brain is creating something like a filter for tinnitus. Even with my earplugs the sound is extremely hard to pick up.
At the start it felt unpleasant but after 1 hour and 15 minutes of listening to it I felt kind of relaxed. Also during the time of listening to this I got some weird stabbing sensations in my tinnitus ear (not painful or anything), I don't know if they mean something.
One last thing worth pointing out is that I didn't use headphones (stashed all of them away around the time I got tinnitus due to horror stories I've read here), but speakers.
It's been around 2 hours since I listened to the audio file, I don't know if residual inhibition still applies or not but my tinnitus is still lower than what it was before. I'm going to start using this when I go to sleep as well and report back.
